Here are three potential PRPs and their liability:

• **ChemCorp:** As the owner and operator of the plant during the period of contamination, ChemCorp is a primary PRP. They generated and disposed of the hazardous waste that caused the contamination, regardless of their intent or negligence.
• **Current Owner of the Property:** Even if the current owner acquired the property after the contamination, they could be considered a PRP under CERCLA. The law holds current owners liable for past actions that caused contamination, regardless of their involvement in the initial disposal.
• **Companies that Supplied Chemicals:** If any chemical suppliers provided materials that were later disposed of in the landfill, they might also be PRPs, especially if they had knowledge of the hazardous nature of the chemicals and the potential for improper disposal.

It is important to note that the specific liability of each PRP would be determined by a thorough investigation by the EPA and potentially through legal proceedings. The EPA would consider factors like the nature of the waste, the extent of contamination, and the knowledge of each party involved.
